The purpose of this study was to investigate the relationship between the burden on families who live with an elderly person suffering from senile dementia, and the degree of their depression. There were 400 participants in this study, staying in the Seoul and Kyonggi areas from August 1, 1997 to February 28, 1998. Among the group, 100 participants took care of their patient at home, and another 300 participants left 100 patient at a day-care center, 100 sanatorium for senile dementia(asylum for helpless elderly people), 100 an infirmary for elderly people. Eventually 242 subjects out of the 400 were selected for the data analysis. The Zarit (1980) tool was employed to measure the degree of burden and Zung's(1965) “Self-Rating Depression Scale” was employed for the data analysis. The data was analyzed, and the percentage, t-test, ANOVA and Person's Correlation Coefficient were calculated. The results are as follows : 1. The average degree of burden that care-giving families felt was 49.13, which is somewhat high. 2. The average degree of depression that care -giving families felt was 51.95, which is relatively high. 3. The degree of burden was directly affected by the relation with the patient(F＝2.48, P＜.05), and the socio-economic status of the family(F＝5.17, P＜.05). Its also affected by the patient's educational status(F＝2.17, P＜.05). 4. The degree of depression of the family was significantly dependent on sex(t＝-2.05, P＜.05), age (F＝2.99, P＜.05), the relationship with the patient(F＝3.65, P＜.01), socio-economic status (F＝7.74, P＜.001), occupation(t＝2.82, P＜.01), health status(F＝4.42, P＜.01), and the place of residence(F＝4.30, P＜.01), The patient characteristics was significantly dependent on his/her educational status(F＝3.85, P＜.01), the period of suffering from senile dementia(F＝2.47, P＜.05), and smoking habit(F＝6.17, P＜.001). 5. The relationship between the degree of burden and that of depression reads r＝0.43, which is statistically positive correlation in the high significant level. Upon analyzing the entire summation, most care-givers for elderly patients suffering from senile dementia lack time in caring for themselves. They also experience chronic fatigue and mental discomfort caused by the isolation from society, curtailment of certain activities, a sense of responsibility for their patients, and limits of their endurance in taking care of their patients over time. In conclusion, this study emphasizes the necessity for the following propositions : 1. In order to measure the degree of burden that Korean care-giving families undergo, a new tool must be developed on the basis of Korean culture. 2. An educational program based on the demands that care-giving families undergo must be developed, and its clinical effect also has to be examined.

This study has the purpose of suggesting the method to analyze the spatiotemporal change of satisfaction concerning the officially assessed land price using geostatistical analysis. Analyzing the spatial distribution characteristic of officially assessed land price using present GIS (Geographic Information System) or is staying at qualitatively suggesting the improvement method of the officially assessed land price system. Grouping the appeal strength based on the official price and opinion price of officially assessed land price, GIS DB (Database) was constructed and the time seriate satisfaction were analyzed and compared through spatial density analysis and spatial autocorrelation analysis. As a result, it was found that the difference between the official price and the applicant's price differed depending on individual land, but most of the respondents requested the increase or the reduction of the average land price, which resulted in a large number of request. Analyzing the satisfaction of the officially assessed land price by using GIS, it was known that satisfaction of officially assessed land price could be analyzed by using the difference of the opinion price and not only the officially assessed land price. Spatiotemporal change of officially assessed land price satisfaction was known to be possible through spatiotemporal pattern analysis method such as spatiotemporal auto-corelation analysis and hotspot analysis etc using GIS. In short, regionally positive or negative significant relationship was investigated through spatiotemporal analysis using annual data.

Objectives : This research was performed to investigate the effects of Hwangryunhaedok-tang decoction and Hwangryunhaedok-tang Pharmacopuncture at BL10 on cognition and memory impairment in a mouse dementia model induced by scopolamine. Methods : Fifty ICR mice were divided into 6 groups : Normal group (n=5), Control group (n=9), Positive control group for pharmacopuncture group (n=9, Donepezil 0.75 mg/kg), Positive control group for oral administration group (n=9, Donepezil 5 mg/kg), Pharmacopuncture group (n=9, Hwangryunhaedok-tang Pharmacopuncture undiluted solution 10 ml/kg), and Oral administration group (n=9, Hwangryunhaedok-tang 200 mg/kg). For a mouse dementia model, 1 mg/kg scopolamine was intraperitoneally administered to ICR mice. Hwangryunhaedok-tang pharmacopuncture was administered on BL10 for 4 weeks at intervals of 2 days. Hwangryunhaedok-tang decoction was given orally for 4 weeks every day. Morris water maze and passive avoidance test were conducted followed by measurement of acetylcholine concentration, acetylcholinesterase activity, and the amount of BDNF and p-CREB in the brain. Results : 1. In the Morris water maze test, the time spent staying around the platform significantly increased in the pharmacopuncture group and oral administration group than in the control group. 2. In the passive avoidance test, the time spent in the bright room significantly increased in the pharmacopuncture group and oral administration group than in the control group. 3. The level of acetylcholine in brains increased in the pharmacopuncture group and oral administration group than in the control group. Also, the activity of acetylcholinesterase decreased in the pharmacopuncture group and oral administration group than in the control group. 4. The expression of BDNF and p-CREB decreased in the control group, but increased in the pharmacopuncture group and oral administration group. Conclusions : These results suggest that Hwangryunhaedok-tang decoction and Hwangryunhaedok-tang pharmacopuncture at BL10 may have cognition and memory-enhancing effect in scopolamine-induced dementia in ICR mice via controlling the content of acetylcholine and the activity of acetylcholinesterase, and activating BDNF and p-CREB.

The offshore plant crews that were commissioned in the commercial startup phase boarded the offshore plant in two shifts until the end of the project. The crews who were hired by the owner side stayed in the original offshore plant during the project. However, most of the offshore plant commissioned members who were dispatched from the shipyard were accommodated in the offshore accommodation barge. For this reason, they were exposed to many accidents since there are a lot of people staying in a small space. This study suggested a method for improving survival rate at offshore accommodation barge in terms of life safety. It is assumed that the fire accident among unfortunate events which take place in the offshore accommodation barge mainly occurred. So, this study analyzed the safety evacuation for offshore plant employees using fire simulation model based on both domestic and international law criteria. In particular, When fire occurs in the offshore accommodation barge, the periodically well trained crews are followed safety evacuation procedure. whereas many employees who have different background such as various occupations, cultural differences, races and nationality can be commissioned with improper evacuation behaviors. As a result, the risk will be greater than normal situation due to these inappropriate behaviors. Therefore, This study analyzed the Required Safe Escape Time (RSET) and Available Safe Escape Time (ASET). Also it was suggested the improvement of structure design and additional arrangement of safety equipment to improve the survival rate of the residents in offshore accommodation barge.

In order to find out the condition of flow in sewer pipes, this study investigated the characteristics of tractive force of sewage flow estimated using actual measured values of water level, velocity, and flowrate in sewers located at uppermost portion in a treatment area during dry weather periods. When the scene of sewage flow was taken by CCTV after cohesive and non-cohesive solids (tofu and sand) were put on the sewer invert, it was found that the solids could be flushed without significant interruption. In sewer with slope of 0.00319, the frequency exceeding the minimum tractive force of sewage during a weekday was zero, while it was 10 per day with slope of 0.00603. During the week of the field observation, the event to exceed the minimum tractive force occurred once, suggesting that sewer odor would potentially increase. Maximum tractive force in sewer with steep slope was 2.9-3.1 N/㎡, but with gentle slope it decreased to 1.6-1.7N/㎡. It was also observed that the interval of time maintained below the criterion of minimum tractive force increased, during weekends compared to weekdays and for the sewage including non-cohesive particles which could enter combined sewers during a storm period. This study found that the sewer sediments formed by direct feces input into sewers, through sewer pipes which were designed meeting the standard sewer design criteria, could be flushed without staying as deposited solids state for a long time.

Background: Cerebral palsy (CP) is non-progressive disorder of motion and posture. In CP patient, there are difficulties in dental treatment because of uncontrolled movement of limb and head, and conjoined disabilities such as cognitive impairment, sensory loss, seizures, communication and behavioral disturbances. It is reported that CP patients have high incidence in caries and a higher prevalence of periodontal disease. But, despite the need for oro-dental care, these patients often are unlikely to receive adequate treatment without sedation or general anesthesia because of uncontrolled movements of the trunk or head. Methods: We reviewed the 58 cases of 56 patients with CP who underwent outpatient general anesthesia for dental treatment at the clinic for the disabled in Seoul National University Dental Hospital. Results: The mean age was 19 (2-54) years. The number of male patient was 40 and that of female was 18. They all had severe spastic cerebral palsy and 22 had sever mental retardation, 15 epilepsy, 8 organic brain disorder, 1 blindness, 2 deafness and cleft palate. For anesthesia induction, 14 cases was needed physical restriction who had sever mental retardation and cooperation difficulty, but 44 cases showed good or moderate cooperation. Drugs used for anesthesia induction were thiopental (37 cases), sevoflurane (14 cases), ketamine (3 cases ) and propofol (4 cases). All patients except one were done nasotracheal intubation for airway management and 4 cases were needed difficult airway management and 1 patient already had tracheostomy tube. Mean total anesthetic time was $174{\pm}56$ min and staying time at PACU was $88{\pm}39$ min. There was no death or long term hospitalization because of severe complications. Conclusion: If general anesthesia is needed, pertinent diagnostic tests and workup about anomaly, and appropriate anesthetic planning are essential for safety.

Purpose: The study examined the poisoned patients' characteristics nationwide in Korea by using data from the National Emergency Department Information System (NEDIS). Methods: Among the patients' information sent to NEDIS from January 1, 2013 to December 31, 2015, the included subjects' main diagnosis in ED showed poisoning according to the 7th edition of the Korean Standard Disease Classification (KCD-7). We analyzed the patients' gender, age, initial vital signs, visit time, stay time of staying in ED, results of ED care, main diagnosis in ED, length of hospitalization, and results of hospitalization. Results: A total of 106,779 ED visits were included in the analysis. There were 55,878 males (52.3%), which was more than the number of females. The number of intentional poisoning was 49,805 (59.6%). 75,499 cases (70.8%) were discharged, and 25,858 cases (24.2%) were hospitalized. The numbers of poisoning patients per 1,000 ED visits were 14 in Chungnam and 11.9 in Jeonbuk. The most common cause of poisoning, according to the main diagnosis, was venomous animals. It was the same for hospitalized patients, and pesticide was next. Pesticide was the most common cause of mortality in ED (228 cases, 46.1%) and after hospitalization (584 cases, 54.9%). The incidence of poisoning by age group was frequent for patients in their 30s to 50s, and mortality in ED and post-hospitalization were frequent for patients in their 60s to 80s. Conclusion: This study investigated the characteristics of poisoning patients reported in the past 3 years. Pesticide poisoning had a high mortality rate for patients in ED and in-hospital. For mortality, there was a high proportion of elderly people over 60. Thus, policy and medical measures are needed to reduce this problem. Since it is difficult to identify the poison substance in detail due to nature of this study, it is necessary to build a database and monitoring system for monitoring the causative substance and enacting countermeasures.

As of the end of the year 2016, the foreigners staying in Korea have surpassed 2 million people for the very first time ever since the statistical writings began. Because the inflow of the foreigners has been greatly increased within a short time period, the Korean society has been rapidly changing into a multi-racial and multi-ethnic society, and the children of the multicultural families, too, have been increasing gradually. Because of the social prejudices, discriminations, negative recognitions, etc., the children of the multicultural families get exposed to the diverse problems. It can be considered that such social prejudices and negative recognitions comprise the discourses that are possessed by the constituent members of the society regarding a certain subject or phenomenon. By analyzing the special characteristics and discourses of the reports on the multicultural children and youths by the Korean press through newspaper articles, this research confirmed what influences the media have in the process of forming the recognitions regarding the multicultural children and youths at present. As a result of the research, the discourses appearing in the newspapers could be typed into the support emphasizing frame of the Korean society, the adaptation emphasizing frame of the Korean society, the global people of talent frame, the change emphasizing frame of the Korean society, and the social problem emphasizing frame. Based on such research results, I made a proposal regarding the direction for the desirable reports by the media.

The diurnal pattern of leaf water potential in cuttings by Dye Method was as follows: 1. Diurnal pattern of leaf water potential (${\psi}_l$) in Viburnum Awabuki K. Koch and Daphne odora Thunb. was shown the pattern of the curves without mutual relation with soil classes when soil water potential (${\psi}_s$) was 0 bar. When ${\psi}_s$ was above -0.01 bar, the cuttings in the loamy sand (L.S.) was shown by the maximum values than that in sandy clay (S.C.) by about -1 bar gap (Fig. 1). 2. The diurnal changes of ${\psi}_l$ was shown the most high from two to eight O'clock in the morning, the maximum value was -3 bars when ${\psi}_s$ was above -0.01 to -0.02 bar, and was -4 bars below -0.03 bar. The diurnal the lowest values of ${\psi}_l$ showed -20 to -22 bars from one to two O'clock in the afternoon. In the fifteenth day after cutting V.A., the staying time in the diurnal maximum values of ${\psi}_l$ is about half in comparison with it in the fifth day. The curves of recovery of water stress (Fig. 1), the former reached to the diurnal maximum values -1 to -2 bars lately every hours comparing with it of the latter. The general diurnal pattern of ${\psi}_l$ was most clearly related to change with air temperature and the relative humitidy. 3. Comparing the treatment block by IAA 50 ppm with controlled block in fifteenth day after V.A. cuttings, in case of treatment reached to maximum values -2 to -3 bars lately as shown Fig. 2., and also staying times was only half in comparison with controlled block. 4. The cuttings 4 leafs was much rootings than 2 leafs in V.A. (Table. 1), and the former reached maximum value -2 to -3 bars lately every hours comparing with the latter. 5. In case of Buxus microphylla var. Koreana as shown Fig. 3., comparing the pattern curves of in the cuttings 8 leafs with 4 leafs, the former reached to maximum values -2 to -3 bars lately in comparison with the latter, but reffering to the amount of rooting (Table. 2), the former is less than the latter.

This study was carried out to investigate the drinking patterns of sap water of Acer mono by on-the-spot visitors. The survey was done from late-February to mid-March in the 3 major sap water tapping regions, such as Piagol of Mt. Chiri in Kurey, Okryong of Mt. Baekun in Kwangyang, and Mt. Chokey in Sunchon, Chonnam. A total of 300 visitors over 20 years old, 100 visitors in each region, were interviewed personally to make up questionnaires, irrespective of sex. The purpose of drinking, the frequency of visit, the modes of traffic, the length of stay, drinking amount per person, one's opinions after drinking, drinking plans and patterns, and intention of drinking processed sap were investigated and examined. Wide range of age groups from twenties to sixties drank sap water. Visitors drank sap water in order to keep health, to promote mutual friendship, and so on. 44% of sap drinkers visited for the first time, and 71% visited by private automobiles holding the first place. 59.7% of visitors spent only a day, but 40.3% passed one or two nights to drink sap water. For drinking amount of sap water, $3-6{\ell}$ a was consumed by 31.3% of visitors, under $3{\ell}$ or $9-12{\ell}$ by 22.7% $6-9{\ell}$ by 12.7% and so forth. 74% of visitors felt sap water sweet and favorable, but were doubtful about the efficacy of sap water. 79.0% of visitors had a plan to drink sap water again next year, 40% of whom preferred a day's visit to overnight staying (29%) or 3 days' staying (6%). 45% answered to plan to drink sap water with having meals, and 43% with having meals and passing a night. More than half (54.3%) of the visitors were inclined not to drink processed sap water for the reasons of unreliable quality, unwillingness for process, change in quality, etc.
